    Abstract: A medical device system may include an elongate shaft having a lumen extending from a proximal end to a distal end, a proximal release wire, and a distal release wire. The proximal release wire may extend distally from a proximal end configured to remain outside the body to a distal end and may be slidably disposed within the lumen of the elongate shaft. The proximal release wire may include a distal stopper coupled to the distal end thereof. The distal release wire may extend distally from a proximal end to a distal end and may be slidably disposed within the lumen of the elongate shaft. The proximal end of the distal release wire may be slidably coupled to the distal end of the proximal release wire. The distal release wire may be configured to releasably attach a medical device to the distal end of the elongate shaft.

    Abstract: A medical device for left atrial appendage closure includes a support frame with a proximal collar and a distal collar, where the support frame is actuatable from a first constrained configuration to a second radially expanded configuration. A membrane is disposed on at least a portion of the support frame, and an engagement element is coupled to the distal end region of the support frame. The engagement element extends distally from the support frame and is configured to engage an inner surface of the left atrial appendage and prevent the support frame from sliding along the inner surface of the left atrial appendage during implantation.

    Abstract: An occlusive medical device system may include an elongate shaft having a lumen extending longitudinally through a tubular body portion and a plurality of retaining arms extending distally from the tubular body portion. An occlusive medical device may include a proximal tubular mounting portion fixed to an expandable occlusive element. A release wire may be axially translatable between a distal engagement position and a proximal released position, the release wire having a distal engagement portion and a distal retention portion distal of the distal engagement portion. The distal engagement portion may be configured to engage the plurality of retaining arms in the distal engagement position, thereby urging the plurality of retaining arms into releasable engagement with the proximal tubular mounting portion, wherein when the release wire is in the proximal released position, the plurality of retaining arms is deflectable radially inward to disengage from the proximal tubular mounting portion.

    Abstract: Embolic material delivery devices and methods of using them are disclosed. An example embolic material delivery assembly includes an outer member having a lumen extending therein and a distal end region, an inner member disposed within the lumen of the outer member, wherein the inner member includes a first lumen extending therein. The embolic material delivery assembly also includes a first embolic material extending within the first lumen of the inner member, the embolic material having a first distal end region. The embolic material delivery assembly also includes an anchor disposed within the lumen of the outer member, the anchor having a first attachment region. Further, the first distal end region of the first embolic material is coupled to the first attachment region of the anchor.

    Abstract: An occlusive medical device such as a vascular implant includes a terminal portion including a first plurality of strut segments that are each joined together at a distal end thereof to form a closed end of the frame, an intermediate portion including a second plurality of strut segments, the second plurality of strut segments including a greater number of strut segments than the first plurality of strut segments, and a main portion including a third plurality of strut segments, the third plurality of strut segments including a greater number of strut segments than the second plurality of strut segments. The occlusive medical device may have an expanded configuration in which the second plurality of strut segments and the third plurality of strut segments together form a plurality of cells.
